Lawyers hired to help Utah prepare a $14 million lawsuit against the federal government for control of public lands billed the state for first-class airfare, stays at luxury hotels and steakhouse meals, according to invoices flagged Wednesday by a watchdog group.

Anne Weismann, executive director of the Washington, D.C.-based Campaign for Accountability, said the expenses flagged by her group show sloppy accounting at best and a serious abuse of taxpayer funds at worst.

"Either way, Utah taxpayers deserve a full accounting of the expenses," Weismann said in a statement. "If there is a good reason for these lawyers to bill the state of Utah for luxury hotels, let's hear it."
